Short circuit due to improper connection

An incorrect connection of the power supply will destroy the electronics and void the warranty.

Storage at an excessively high temperature

Store the APEX (SILAS) pressurized cabinet at the intended storage temperature since otherwise damage to the electronics or seals may occur.

Ensure adequate air conditioning at high storage temperatures.

Aggressive cleaning agents

When selecting the correct cleaning agent, it is essential that it is suitable for use since otherwise damage may occur to seals and connections.

Combustible products are generally not permitted.

Danger to health due to improper disposal

According to the European WEEE Directive, electrical and electronic equipment may not be disposed of with household waste. Their components must be sent separately for recycling or disposal because toxic and hazardous components can cause long-term damage to health and the environment if not disposed of properly.

As consumers, you are obliged under the Electrical and Electronic Equipment Act (ElektroG) to return electrical and electronic equipment at the end of its serviceable life free of charge to the manufacturer, the point of sale or to public collection points set up for this purpose. Details of this are regulated by the respective national law. The symbol on the product, the operating instructions or/and the packaging refers to these regulations. With this type of material separation, recycling and disposal of old devices, you make an important contribution to the protection of our environment.

Product description APEX / SILAS

Pressurized Cabinet


3 Product description General

The Ex p type of protection, referred to as “pressurized enclosure”, is based on the measure of purging out any explosive gases that are in a closed enclosure and then generating and maintaining a level of pressure that is higher than that of the ambient atmosphere. As the pressure inside the enclosure is higher than the atmospheric pressure, it is not possible at any time for explosive gases to penetrate the inside of the enclosure. This creates an Ex-free area in which electrical devices that are not themselves explosion-proof can be mounted and operated.

The APEX (SILAS) pressurized cabinets described in these operating instructions function on the principle of “pressurized enclosure with leakage loss compensation”. Specifically, this means that an overpressure in an enclosure is maintained by the addition of purging gas to compensate for the leakage losses from the enclosure. In addition a defined quantity of purging gas can be introduced also during the operating phase, depending on application; constant purging.

To ensure that an explosive atmosphere that has penetrated during downtimes cannot become a hazard, the pressurized cabinet must be flushed with purging gas (compressed air or inert gas) before commissioning. The quantity depends on the inspection carried out during initial commissioning. The rate of flow is measured or determined at the outlet of the pressurized enclosure.

After purging, the Ex p protected application is switched on. Depending on version of the APEX (SILAS) pressurized cabinet, the activation may take the following form.

APEX pressurized cabinet type, pxb Automatic connection via the Ex p control unit or, in the case of larger switching capacities, via a separately certified switching module or indirectly from the Ex safe area.

APEX pressurized cabinet type, pyb Automatic connection via the Ex p control unit or, in the case of larger switching capacities, via a separately certified switching module or indirectly from the Ex safe area.

The automatic connection can also be realised by manual connection, whereby the switching module must be certified separately.

SILAS pressurized cabinet type, pzc Automatic connection via the Ex p control unit or, in the case of larger switching capacities, via a separately certified switching module or indirectly from the Ex safe area.

The automatic connection can also be realised by manual connection, whereby the switching module must be certified separately.

Commissioning APEX / SILAS

Pressurized Cabinet


7 Commissioning

Initial commissioning

Before the APEX (SILAS) pressurized cabinet is put into operation, a first test must be performed.

See IEC/EN 60079-14 for the first test.

Putting into operation

The APEX (SILAS) pressurized cabinet has an automatically functioning Ex p control unit. This means that after applying the supply voltage and activating the purging gas supply, the system automatically starts the operation of the Ex p phases.

Type 0(A)7-3704-1***/**** (gas/dust)

To put the APEX (SILAS) pressurized cabinet into operation, proceed as follows:

- Dust the enclosure

- Make sure that the operating pressure of the purging gas for the pressurized encapsulation is set at the pressure reducer station to the pressure specified on the type plate.

- Make sure that the discharged purging air at the pressure monitor outlet is discharged into a safe zone.

- Close and lock the main door of the APEX (SILAS) pressurized cabinet.

An overpressure is then built up in the pressurized enclosure due to the inflowing purging gas.

As soon as the inner pressure exceeds the set minimum limit, the purging time starts to count down. After expiry of the purging time, the internally protected assemblies and components are switched on as follows:

APEX pressurized cabinet, type “pxb“: the internal fitted components are automatically switched on.

APEX (SILAS) pressurized cabinet, type “pyb“ and “pzc“: the internal components are either switched on automatically or manually by the operator.

The APEX (SILAS) pressurized cabinet is ready for operation from this point in time.

Operation APEX / SILAS

Pressurized Cabinet


8 Operation Operating phases of the APEX (SILAS) pressurized cabinet

The operation of the APEX (SILAS) pressurized cabinet can be divided into three phases, which are preparatory, purging and operating phase.

Process diagram of the operating phases

The APEX (SILAS) pressurized cabinet is built in compliance with the currently applicable guidelines and standards and fulfils the requirements specified therein. The processes in the respective states are listed in the following.

Operating phase Requirements Effects

Preparatory phase

- Mains voltage connected - Build-up of internal pressure - Purging time set - Purging time has not yet

expired

Initiation of the purging phase

Purging phase (not applicable for dust)

- Minimum pressure ok - Maximum pressure ok - Flow rate ok

Purging time is running

Operating phase - Purging time has expired - Minimum pressure ok - Maximum pressure ok

Operation enabled

Preparatory phase

The preparatory phase begins when the supply voltage for the APEX (SILAS) pressurized cabinet and the supply with purging gas is switched on. The purging gas flows through the purging gas valve into the APEX (SILAS) pressurized cabinet.

Preparatory phase sequence:

The influx of purging gas increases the internal pressure in the pressurized enclosure.

The minimum pressure of the enclosure is exceeded.

The purging gas valve opens.

In the case of dust applications, the purging gas valve is replaced by the adjustable needle valve.

The next phase, the “purging phase“ is initiated.

APEX / SILAS

Pressurized Cabinet Operation


Purging phase

The pressurized enclosure of the APEX (SILAS) pressurized cabinet is purged with purging gas in order to remove any explosive gas-and-air mixture inside or to dilute it to a harmless concentration before the possible sources of ignition are connected and activated in the pressurized enclosure.

This process prepares the pressurized enclosure for the operating phase. The necessary purging volume depends on the free capacity of the pressurized enclosure.

Purging phase sequence:

Increase in the flow with purging gas.

The set purging time counts down and the APEX (SILAS) pressurized cabinet is purged with purging gas.

At the end of the purging time, the purging gas valve closes.

The next phase, the “operating phase“ is initiated.

This phase is not applicable for dust applications because it is replaced by the prior cleaning of the switch cabinet from dust.

Operating phase

The operating phase begins when the purging gas valve closes.

The operating pressure must be maintained throughout the entire operation of the pressurized enclosure to prevent the penetration of combustible substances. The electrical installed parts in the pressurized enclosure are connected and activated by means of the Ex p control unit.

If the enclosure pressure drops below the set minimum levels during the operating phase, all electrical installed parts in the pressurized enclosure which are not themselves explosion-proof, are switched off and the purging process starts again.

In the case of the “pyb“ and “pzc“ types with manual switching on and off, the deactivation must be performed manually. The message is given via a visual and/or audible signal.

Operating phase sequence:

The purging value closes and the leakage losses are compensated.

The Ex p control unit activates the pressurized enclosure of the APEX (SILAS) pressurized cabinet.


Pressurized Cabinet


Purging time

CONSTANT PURGING AIR SUPPLY When counting down the purging time it is important that the available purging air is constant in terms of pressure and flow. Otherwise, the purging time may be reset automatically.

Pay attention to the purging air supply and its layout

The APEX (SILAS) pressurized cabinet can have a manual or automatic purging time calculation.

It is delivered as standard with a manual purging time. In the version with automatic purging time calculation, this is shown on the type plate.

Manual purging time

In the case of manual purging time, the corresponding Ex p control unit has a permanently set purging time which only expires once the corresponding flow rate has been reached and the corresponding parameters have been exceeded.

Automatic purging time

In the case of automatic purging time, the parameters of volume and applied outlet are stored in the Ex p control unit. During the booting of the Ex p control unit the purging air flow rate achieved during the first 10 seconds is determined and the corresponding purging time calculated, set and run. After expiry of the purging time, the Ex p control unit is in normal operating mode.

APEX / SILAS

Pressurized Cabinet Operation


Bypass operation

DANGER

COMMISSIONING WITH BYPASS KEY SWITCH IN EXPLOSIVE ATMOSPHERE

Risk of explosion!

Have the commissioning with a bypass key switch approved by the factory manager or his appointee. Approval may only be given if it has been ensured that there will not be any explosive atmosphere for the duration of the commissioning or if the necessary precautions have been taken to protect against the risk of explosion (fire permit).

A warning sign informing that the Ex protection will be invalidated if the key switch is activated must be affixed near the key switch.

During the operating phase it may be necessary to change settings on internally mounted components. The Ex p control unit provides the bypass function for this purpose.

If the bypass mode is activated, it must be ensured that there is no explosive gas in the atmosphere. The concentration of gas in the surrounding atmosphere must be determined with a gas detector.

Once the bypass mode is activated, the door on the pressurized enclosure can be opened without interrupting the operation of the internal components. The required settings can be carried out and, once done, the pressurized enclosure must be closed again. The operation of the pressurized enclosure is not interrupted for this duration. The purging phase for the pressurized enclosure is not repeated.

Procedure:

- Measure the ambient atmosphere for compliance with safe levels.

- Activate bypass operation.

- Open the door of the pressurized enclosure.

- Perform the required work inside the pressurized enclosure.

- Close the door of the pressurized enclosure.

- Deactivate bypass operation.
